Inside the issue - which is available for just £2.99 on your iPad - Gillan discusses preparing for the role of Nebula.
"I started off with just working out," she says. "They wanted me to just look a bit tougher. I started eating lots of protein. I went on this diet of more food, rather than less... I was like, 'You want me to eat everything? Perfect!'"
Gillan adds: "These women character are just so fierce. The fight sequences aren't graceful – they're hard and strong."
Guardians Of The Galaxy opens in the UK on 14 August 2014.
